Can you please run the command with DEBUG=corepack set in your env?

Can you please run the command with DEBUG=corepack set in your env?

Sure. You can see from the working one that the env file is loaded after the install.

Yeah it looks like .corepack.env is completely ignored when running corepack use, looks like an oversight. Any chance you would like to submit a patch for this?

I'm not familiar with the repo, but I can give it a try.
